If you look closely at a bar code it has '666' on it. Now if you want to be ignorant on the whole thing and be rediculous thats fine. Not my place to judge you that is God's, but i would suggest you watch yourself before the anti-christ comes along and you think its some joke and you put that crap on you only its permanant and wont wash off like pen. That is why you SHOULD NOT take it lightly.
